and it'has for its object an improvement on an ordinary type'ot fluid separator such as that illustrated and described in the Patent No. 1,3365870 issued to- H; Tracy, April 13,

1920. My improvement consistspartly in more suitablyproportioning certain parts of a fluid" separatorof this general types 1 Of the drawings; Fig. 1 isa cross sectional view ofa fluid-separathr or purifier which en 1 bodies the features of my invention; F-1g.21s

a a central transverse section of the purifier; Fig. 3 is an elevation ofia purifier mounted in a boiler forflopera'tion, the purifier consisting of eight sections; and Fig. 4 is an enlarged central sectiouarview of aportion ofthe purifier similar to' Fig; 3', but comprising three sections-only.

The separatcr which I have illustrated is ordinarily installed in? the steam boiler 110 and the separatorcofmprises acasing l'll which forms the exterior portion of the separator. Tothiscasing' areattached cartons 112 of baffles 113 which dry and *purify the steam or gas as it passes frorn the boiler through the baifles to the interior chambers. From the separator the steam passes out of the boiler through an outlet 114 which is connected to the steamsupply mainl of the boiler. The steam passes from thebafiles 113 into the chamber 115', through the slotpa'ssageway 116, intb the interior conduit or chamber 117; andth'ence' into the separator outlet 108 and the boiler outlet 11 1.

The interior chamber 117 is enclosed by a casing comprising- Walls 118 'forming its sides and a bottom 119 and over the chamber is a plate 120 which is elevated above the side Walls so as to form the slot 116 through which the steam enters the interior chamber. In practice the separators are of considerable lengthandfiiequenfly comprise several sections as indicated inFig; 3Whichhasfour sectionson one side of the outlet and c0rre spondin'g' sections on the-other side ot-the outlet. The slots llfiextend substantially the full length of each section andform an inlet for the steam from the bafiles. The baflles extend substantially from the steamoutlet 108 tothe remote end of the farthest'section. The steam, however, entering" this slot inlet 116 must all pass through the'passageway 117 to-the outlet 108.

Asua' consequence of this arrangement, there isa tendency for the steam to pass" through the bafiles more rapidly as the outlet 1 is approached, because of the back pressure generated in thechamber 117 being less1nearer the outlet. To offset this it hasbe'en found desirable to taper the slot inlet 11 6 by decreasing the: Width ofthe slot as'theoutlet is approached so as to restrict more andmore thefiow of the steaminto the interior chamber. It is desirable to maintain at all ti-mes substantially a uniform rate of flowvof the steam through the bafiies; and inzorder to accomplish this' I find'it desirable to not only provide a tapering: slot for the steamin'let, increasing the'elevation of the plate'120 as the outer end of theseparator is: approached; but also to increase this elevation-at a rate grelateri than the-rate of approach to the outer en In practice it is not convenienttonchange the rate of increase in the elevation of alny of the" uppermost plates as the outer end is approached, and hencel have not soshown it in the drawings, but theoretically there should be aslightly greater elevation in pro portion to the distance from the'steam outlet as the outer free endofthe-purifier is'ap preached. In practice thisean be approximated by increasing the inclination of each plate 120 from-section to section, havingthe inclination of the plate of thesecond section more than thatof the first sectionand of the third section more than that of theseco n'd and so one In Fig. 4 I -haveshown thr'ee sections 1th this varying inclination of the plate 120. It will beseen-thatthe inclination of the plate of the outer section 125 is greater than the inclination of the plate of the section 126, and the inclination of the plate of section 126 is greater than the inclination of the plate of section 127. In this way the rate of flow through the baflles in the difi'erent sections is more nearly equalized. It is to be understood, however, that to substantially equalize the flow through the baflles it would be necessary for slot 116 to continu ously enlarge at a greater rate than the distance from the outlet.

It is desirable to very rapidly enlarge the inlet adjacent the outer end of the outer section so as to increase the steam flow at this end. In practice, therefore, it is desirable to have the sides 118 and 120 of the outer section terminate before reaching the outer end of the section, (Fig. 4), so as to leave a very large passageway 129 for the steam at this point. Ordinarily I prefer to have these sides terminate about 6 from the end of the end section, and to have the width of the slot at this point about 1. It will be understood, however, that these dimensions are merely for illustrating and approximate only what a good slot arrangement would be for the purifier of the other dimensions specified.

Although I have described with much particularity a fluid separator to be used for purifying steam, yet it is to be understood that separators having slots substantially as herein set forth for the passage of the fluid therethrough could be used for various other purposes, such as eliminating impurities from various other gases, and separating fluids of different densities. Also other eliminating apparatus for the passage of fluids could be used with similarly proportioned slots, for instance, apparatus for ventilating rooms by withdrawing the air uniformly into an elongated cooler, having an end outlet; or apparatusfor injecting air into a room; or apparatus for the purpose of withdrawing a mixture of liquids uniformly along its length, and various other apparatus. It is understood that the illustrations herein made are merely for the purpose of definitely describing my invention.

I claim:

A gas purifier comprising an elongated casing having a gas outlet ad acent one end and a gas inlet extending along one side of said casing, said inlet having purifying means mounted therein, and means for retarding the flow of gas mounted in said casing,sa1d means comprising plates forming an inner chamber, said plates having an elongated slot therein, the end of said plates most remote from said outlet being spaced a material distance away from the adjacent end of the casing.

2. A fluid separator comprising an elongated casing, a series of baflles mounted in one side of said casing, said casing having an outlet adjacent one end thereof, and gas retarding means mounted between said baflles and said outlet, all of said retarding means being spaced a material distance from the end of said casing most remote from said outlet, said retarding means comprising an inner conduit.

4. A fluid separator comprising an elongated casing, a series of baflies mounted in one side of said casing, said casing having an outlet adjacent one end thereof, and gas retarding means mounted between said bafiles and said outlet, all of said retarding means being spaced a material distance from the end of said casing most remote from said outlet, said retarding means comprising an inner conduit, said conduit having an elongated slot running from one end to the other, said slot increasing in Width as said outlet is receded i'rom.

6. A fluid receiver comprising an elongated casing having a fluid outlet, and an elongated fluid inlet, the end of said inlet most remote from said outlet being enlarged relative to the remaining portions of said inlet and extending across the adjacent end of the casing.

7. A fluid separator comprising an elongated casing, a series of baflles mounted in one side of said casing, said casing having a gas outlet positioned a long distance from one end of the casing, an inner conduit extending longitudinally in said casing between said bafiilesand outlet, said conduit communieating with said outlet and extending therefrom towards a remote end of said casing but terminating a material distance before said end is reached, said conduit having a slot in its walls extending substantially from one end to the other.

8. A, fluid separator comprising an elongated casing, a series of bafiles mounted in one side of said casing, said casing having a gas outlet positioned a long distance from one end of the casing, an inner conduit extending longitudinally in said casing between said bafiles and outlet, said conduit communicating with said outlet and extending therefrom towards said end of said casing but terminating a material distance before said end is reached, said conduit having a slot in its Walls extending substantially from one end to the other, and said slot increasing in Width as said outlet is receded from.
